Oxidation states of P in H 4 P 2 O 5 , H 4 P 2 O 6 , H 4 P 2 O 7 , are respectively

Options

  1. A+3, +4, +5
  2. B+3, +5, +4
  3. C+5, +3, +4
  4. D+5, +4, +3

Correct answer

A. +3, +4, +5

Step-by-step solution

The value of O.No. of P- atoms in these acids are as follows H 4 P 2 O 5 → 4 + 2 x - 10 = 0 2 x = + 6 x = + 3 H 4 P 2 O 7 → 4 + 2 x - 12 = 0 x = + 4 H 4 P 2 O 7 → 4 + 2 x - 14 = 0 x = + 5
